Factory & Industrial Cleaning in Swansea

Canteens, locker rooms, site offices and walkways on working industrial sites, cleaned around your shift pattern rather than through it.

On a working site the cleaning has to fit around production, not the other way round. Shifts change, machines keep running, and there are areas our staff simply should not walk into unaccompanied.

What we look after is the part of a factory people actually live in during a shift: the canteen, the locker rooms, the toilets and showers, the site offices and the walkways between them. Those are the areas that get noticed when they slip.

At the site visit we go through your induction requirements, PPE, and which areas are in scope. It is better to agree the boundary standing in the building than to assume it later.

What the work usually includes

Exactly what's included is agreed at the site visit. This is the usual starting point.

  • Canteens and mess rooms

    Tables, worktops, microwaves, sinks and floors, the areas under most pressure each shift.

  • Locker rooms and showers

    Sanitised and restocked, which matters most on sites running back-to-back shifts.

  • Toilets and welfare facilities

    Cleaned on a frequency that matches how many people are on site.

  • Site offices

    Desks, floors and glass in the office areas attached to the unit.

  • Walkways and communal areas

    Pedestrian routes and shared space kept clear and clean.

  • Hard floors

    Swept and machine-cleaned where access and safety allow.

How we work on a live industrial site

  • Shift patterns come first, so we agree slots that do not interrupt production.
  • Our staff complete your site induction and wear the PPE your site requires.
  • Scope is agreed in writing, including which areas are off-limits without an escort.
  • Production machinery and process cleaning stay with your own team or a specialist contractor.
  • Hazardous substances on site are flagged at the visit so the right areas are left alone.

What clients say

Real words from businesses we clean for.

  • By far the best cleaning company we have used. They are reliable, professional and always do a fantastic job. We can rely on them every time, and the standard of their work is excellent. We wouldn’t hesitate to recommend them!

  • Really pleased we decided on Celtic cleaning. We were having problems with odour from male toilets which they eradicated. We are happy with the cleaning standards and supervision, and on top of that they never miss a shift. Highly recommend them.

Asked about this service

Can you work around our shift patterns?

Yes. On a working site that is usually essential. Tell us when the changeovers happen and we will build the schedule into the gaps rather than across them.

Do you clean production machinery?

No. Machine and process cleaning normally belongs with your maintenance team or a specialist contractor. We cover welfare facilities, site offices, walkways and communal areas, and we agree that line clearly before starting.

Will your staff complete our site induction?

Yes. If your site requires an induction, PPE or a sign-in procedure, our staff will follow it the same as any other contractor on site.
